2015 BMW 520 2.0L Diesel · D3 KNN

The vehicle presents a stable roadworthiness profile, evidenced by five consecutive MOT passes over the last five years. The most recent test conducted on 30 September 2025 at 166,841 miles resulted in no defects or advisories, indicating a high standard of mechanical maintenance. This lack of recorded failures suggests that the previous owners have proactively addressed wear and tear before it could result in a test failure. The mileage data reflects consistent high-intensity usage, averaging approximately 15,167 miles per annum. Between the August 2021 test at 106,556 miles and the September 2025 test at 166,841 miles, the car covered over 60,000 miles. This steady accumulation indicates the vehicle was likely used for motorway commuting, which generally places less strain on clutch and suspension compared to short city trips, though the total figure of 166,841 miles places it in a high-wear bracket for age-related components. Despite the clean MOT history, a physical inspection must focus on components prone to fatigue at this mileage level in BMW vehicles. A buyer should scrutinise the front suspension control arm bushes and coil springs for cracking or sagging, as these often degrade under high mileage. The braking system should also be checked for signs of caliper binding or uneven disc wear, as the MOT does not measure the thickness of pads or discs. Given the high annual mileage, checking for oil leaks around the valve cover and cooling system is essential to ensure the engine remains as reliable as the electronic record suggests.
